I've been mulling over this issue for a while now, and thought I'd ask you guys (and girls) if you had any answers for me. I've also done a search and can't find any threads specifically discussing the issue of variable 4K quality on different platforms.
The main question, there will be others later, is... why does 4K on You Tube look so much cleaner and precise than 4K presentations on all other platforms? If I watch something in (supposed) 4K on You Tube it is always as I would expect 4K to look, whereas 4K on Netflix, Amazon, Stan and VUDU is good, but doesn't have the same (almost) jaw dropping clarity of a You Tube video.
Before we go any further, here is the gear I use (all cables are good, and high speed NBN of consistent 95mbs):
Hisense 75N7
Yamaha 3060
Apple TV 4K
Nvidia Shield
All devices are connected via the 3060
Other questions I just can't find answers to:
1. The Yamaha 3060's recent update included Dolby Vision, but the Hisense isn't compatible. The ATV sends Dolby Vision instead of HDR to the amp when watching Netflix. Does this make any difference? Can it be changed if needed?
2. If this is causing an issue, is there a way to only send HDR from the amp to the Hisense?
3. How do I ensure that I am allowing all video to pass through to the TV to allow it to do the upscaling, as I believe the Hisense is capable of doing a better job?
4. When I visit a You Tube channel which supposedly is showing HDR content, is it actually in HDR or just brighter 4K? The TV doesn't register a HDR signal from You Tube. This is when trying on both media players. The TV does receive HDR signal from other platforms on both the Shield and ATV.
Thanks for any help. Oh, and before anyone whinges that I've posted this on a couple of forums...I just can't find answers to these questions, so I'm covering all knowledge bases.
Cheers
